AVR UC3 Series Software Framework: ABDAC Driver

Copyright © 2007 Atmel Corporation

Introduction

The Audio Bitstream DAC converts a 16-bit sample value to a digital bitstream with an average value proportional to the sample value. Two channels are supported, making the Audio Bitstream DAC particularly suitable for stereo audio. Each channel has a pair of complementary digital outputs, DATAn and DATANn, which can be connected to an external high input impedance amplifier..

 

ABDAC Driver

The driver is composed of abdac.c and abdac.h.

 

An example is available: The given example is a transfer of an input streaming buffer of audio samples on the ABDAC using PDCA. The ouput is Amplified by a TPA6130A2
